JERSEY HEEL-ATTACHING MAGEIINE Application ined August 4, 192e, serialNo. 127,634,` and ni Great einem April 24, 1926.

-This invention relates to machines for use in attaching heels to shoesand is herein illustrated as embodied in a machine of a typeparticularly adaptedv foi-carrying out the 5 method of Wood heelattaching disclosed in United States Letters lPatent No. 1,615,258,granted Jan. 25, 1927, upon an application filed in the name of MauriceV. Bresnahan, although in various aspects the invention is 0 not limitedto embodiment in a machine of that type nor to use in practising thatmethod. A. machine capable of use in practising the above-mentionedmethod *isl disclosed in my oo pendin'g application Serial No. 54,046, 5filedv Sept. 2, 1925, of Which the present application is a continuationin part. The ma# chine just referred to comprises a clamping y devicefor holding a Wood heel in assembled relation with a shoe mounted on alast, While 0 a hole'lis being bored in the heel through afastener-receiving hole in the last and While a fastener is' beinginserted through' the hole in the last into the hole in the heel tosecure the heel to the shoe during the setting of an adhesive Which hasbeen applied between the heel andthe shoe. Y

The present invention has for one object the provision of an improvedsupporting device arranged to maintain` a last, upon Which the shoe ismounted, in Van upright position with the fastener-receiving hole in thelast extending in aV vertical direction and with the heel in assembledrelation With the shoe.y

porting the forepart of the shoe. The pivotal mount-ingY of. thetableVpermits a shoe supported thereby to be tilted to bring thefasteneireceiving hole in the last into a vertical position, Whereas theyielding mounting of the toe plate permits the latter to yield if Ynecessary to enable the tread face of the heel` of the supported shoe tolie flat` upon thepiv oted table irrespectiveV of differences. in theangular relations of the planes of the tread yieldingly mounted uponsaid'table for sup-V facesof the heel andthe sole. Furthermore,

since thefto'e plate is carried by the pivotally ber for engagingpthecone of a last upon Which a shoe is mounted, a support opposite the lastengaging member' arrangedV to engage the tread surfaces-ofthe'heel andsole of the shoe and toV co-operate'vvith said member to clamp the heelto the shoe, and unitary means for effecting relative adjustment of saidsupport and said last engaging member. In the embodiment of theinvention shovvn inthe drawings, the above described `parts are mountedabove a horizontally disposed portion of a frame Work Which serves as atray or bench and the means for effecting the relative adjustment of theclamping'membersis located above the surface of the'benchy Where it isreadily. accessible tothe operator. As shown the adjusting meanscomprises a hand WheelV havingscreW-threaded engagement With a stem uponWhich one ofthe cooperating clampingmembers is mounted, rotation of thehand Wheel moving said clamping member tovvard or from the vco-o eratincla-m infr.

` Another object` of the invention is to locate successive lasts, uponwhich shoes are mounted, in amanner conducive to uniformity of operationin the attachment of heels tothe shoes. Since the boring and fastenerinsert-- ing-'operations are performed at the heel ends of the shoes,the foregoing object is attained by supportingsuccessive shoes VWith theheel ends of their lasts occupying the same position irres ective ofvariations in the style of lasts and height of heels being operatedupon. Accordingly a further feature of the invention consists in theprovision of meansv yfor subsequently substantially.- in a directionlengaging and supporting alasted shoe having a heel in assembled relationtherewith, and a clamp member forV applying pressure to the cone of thelast, movable into a predetermined position to act as a gage inadjusting said shoe engaging means to support successive shoes with thecones of their lasts occupying the sameV position notwithstandingvariations in the style of the lasts or the height ofthe heels.

' In lorderto prevent the pivotally mounted i shoe supporting table frombeing tilted by the action of the last engaging clamping member yin.applying the clamping pressure, the invention provides for mounting theclamping member for movement from an idle position into a last engagingposition and toward :the axisof pivotvof the table to apply clampingpressure to the top of a last upon which the supported shoe is mounted.

The various features of the invention will be best understood from adescription of the preferred embodiment thereof, illustrated in theaccompanying drawings, in which- Fig.. 1 is a view insideelevation of aheel attaching machine with parts broken away, showing particularly theconstruction of the clamping device Fig. 2 is an enlarged view" in sidevelevation of the clamping device;

y Fig. 3 is a detail view in perspective of the shoe supporting table,parts being broken away to show the manner in which the table isadjusted; and

Fig.v 4 is a rear viewof the mechanism shown in Fig. 2.

VReferring to the drawings, the illustrated device is adapted to operateupon a shoe S 1) having a heel H in` assembled relation therewith, theshoe being mounted upon a last L provided with a fastener-receiving holeX which extends from the'toprof the cone to the bottomk of the heel seatportion of the last. The device comprises a base framework 10 supportingatray or bench 12, a shoe supporting table 14,` which is locatedl abovethe bench or tray, and a last engaging clamping member 70 which isarranged to cooperate with the table 14 to clamp the shoe and theheeland the last together.

The shoe supporting table 14V (Fig. 3) is pivotally connected at 16 to abase 3,8 and comprises a heel plate 18 for engaging and supportinga heelsuch as the heel H of a shoe Si, and a vertically-adjustable toe plate20 forV engaging and supporting the forepart of the shoe.` As shown inFig. 2, thel lower c sideof the plate 20 is provided with a stem Y mi 22which lits into a vhollow projection 24 formed on the forward extremityof theshoe supporting table 14. A plug 26 fills the lower opening in thehollow projection 24 and provides a fixed abutment upon which oneextremity'of a compression spring 28 rests.

rlhe other extremity of the spring 28 bears against the end of the stem22 and tends normally to urge upwardly the toe plate 20, while a slotandbolt arrangement 30 limits the extent of vertical movement which maybe imparted to the toe plate. As before mentioned, the table 14 isvpivoted at 16 for vertical tilting movement, and a compression'spring32 located beneath the'table tends normally to tilt the forepart of thetable upwardly. The extent of this upward tilting movement is limited bymeans of a stop here illustrated in the form ofascrew 36, which engagesthe rear of the table, as best shown in Figs'l and4.f

An advantage of mounting the s hoe supporting` table 14 fortiltingadjustment in the .i

manner described isthatthe stop 3G may be adjustedto cause raising orlowering of the forepart of the table against the action of thev`compression spring 32, thereby permitting a supported shoe to be tiltedto position it so that the hole X in its last will be verticallydisposed. By thus positioning the shoe, the tool which bores the hole inthe heel and the tool which inserts the fastener (each of said toolsbeing powerV driven and constituting a part of the complete heelattaching machine) may be more simply constructed and arranged thanwould be required for operating not only in a vertical direction butalso in directions at an angle to the vertical.

Also, if desired, the table may-be tilted to` facilitate seating of theheel upon the heel seat of the shoe. For example, if the rim of the heeldoes not snuglyrengage the heel seat of the shoe at the breast line, theforepart of the table '14 may be tilted upwardly to force the heelclosely against the shoe .at this point. Similarly, if the rear of theheel does not snugly engage the heel seat of the shoe, the

forward part of the table 14 may be tilted downwardly to raise the rearofthe heel and thereby close any gap which may 'exist between the heelandthe shoe and secure afclose joint in this locality.

Thespring beneath the Vtoe plate 20'permits the latter to yield ifnecessary to enable the tread face of the heel to lie flat upon thetread plate 18 of the table irrespective of differ# ences beween theplanes of the forepart of the sole and the tread face of the heel.

" A back rest46, cupped out to receive the otherwise be attained. VTothe end of permitting horizontal adjustment of the rest 46, the

' A screw 48 (Fig) controls vertical adjustl ment of the rest 46 toaccommodate heels of different heights.

to position similarly the heel ends ofsuc'cesf` sive lasts, the table 14is mounted for vertical adjustment for the purpose of locating the topsurface of successive lasts in the same:

vvertical plane. Accordingly, the base 36 is provided with a screwthreaded stem 50 (Fig.V

3) having a groove 52 extending throughout its length. A smoothly boredsleeve 54 loose-r Y ly surrounds the screw threaded stem 50 and isadapted to be inserted within a hollow boss 56 formed on the lower sideof the tray v12(` (Fig. 2). A set screw 58 extends through the hollowboss and has frictional engage-I ment with the surface of thesleeve 54to prevent relative movement between.' the 5. sleeve and the boss. Asecond hollow sleeve (i0V (Fig. 3) surrounds the inner sleeve54 andis ofshorter length than the sleeve 54:-

so that its lower end may rest upon the'top surface ot the tray12,1thereby providing an A additionalsupporting element for the tableA14. Thusit will. be seen that the innerv and outer sleevesV 54 and 60are rigidly mounted upon the tray 12 and that the stem 50 'carryay B ingthe table 14 may be moved freely through y, the bore of the inner sleeve54 to eiect vertical adjustment of the table. Y A. set screw 66V extendsthroughthe sleeves 54 and 60- preventing` relative movement between themand the end of the screw 66 has frictional engage-t nient with thebottom of the groove 52. Y By.

means of the screw 66 .the table 14m-ay be locked in a desired vertical'adjustment Vand rotation of the stem 50 within thel sleeve 54 isprevented.4 i

j The structure defined in the preceding par.` i agraph provides a wayinwhich the table 14V may be manually adjusted to various heights. Inaddition to the provision of means for manually adjusting the table, ahand wheel 68 has been provided for effecting. mechanically thisadjustment; The hand wheel 68 Y a clamping. memberO" (Figsg 2 and y4)which is mounted. for movement toward and away? is screw threadeduponthe stem 50and rotation of the wheel causesthe table 14. to beraised or lowered as desired.- It will be appreciated, inasmuch as thehandY wheel 68 is located above the surface of the tray 12, that itprovides a simple and' easily accessible means for effectingsimultaneously, vertical adjustment of the tread plate 18,- the toeplate- 20 and the heel rest 416. g'

clamp by standing on treadle 92, yet, if desired, as an alternativeconstruction, a shoey may be held under clamping pressure, by means of apawl 110 (Fig. 1) engaging-a ratchet 112 carried by a brace 114. I Thepawl 110 is herein illustrated in the form of an auX- iliary treadle 116pivotally mounted at 111 Aupon the treadle 92A and is held againstratchet 112 by-means of a spring 1,18. Thus depres- 'sionv of thetreadle 92 causes the clamping member 7 0 to be locked inits downwardpo-` sition by reason of pawl 110 engaging ratchet 112r and depressionof the'treadle 116 causes y the pawl 110 to move out of engagement withthe ratchet 112 to release the treadle'92 .and permit upward movement ofthe clamping member 70..` Y

. The device is provided with a latchV or gage 120 for use in setting upthe clamping device Whenever a change occurs in the style of the last orheight of the vheel being operated upon. The latch 120, whichis shown inits inoperative position in Fig. 1, is movable into the position shownin Fig. 4 to straddle the inner projecting end `of thespindle 76 uponwhich the arm 7 2 is pivotallyV mounted.

When theA spindle 7 6is so` straddled by the gage 120, the clampingmember 1 70- occupies an operative gagingV position, preliminaryv toapplying pressure; Vthe. member-f70-has moved from thedotted lineposition of Fig.'

2, across the top of the arc through which itv isconstrained to move,and occupies the fullv line position shown in Fig. 2. Further mover.

ment of the member'O, from its position, takes placeV substantiallyalongl the line AB (Fig. 2) and substantially in thevdirection of theaxis of pivot 16 of the table 14. As already pointed out, the ylatch 120is arrangedto hold the'memberr() in its gag-V ing position. Then soheld, the operator `of the machine places the shoe, for whichhe issetting the clamping: device, beneath the bar 70, with the serratedprojection formed onthe bar engaging the cone forward of the perforationpassing'through the last, and ina position toavoid interference with thej ack-- pin hole. Next the hand wheel68 Vis rotated to cause elevationof the table 14 until both thetread surface of thel heel and the soleofthe shoe are engaged and-supported. Vhen this haspbeen done, the yshoeis held againstvertical displacement and the vertical position ofthetable relatively to the bar 70 is determined. The horizontal position ofthe rest 46 is-then determined by moving the restV intoengagement withthe1 rear of the heel H.

lYhen the vertical and horizontal adjustments have both been made, thelatch 120 is moved.V back into itsidle position and the clamping" deviceis then ready to operate in the same manner upon any number of shoes ofthe same style and height of heel for which the device I has beenadjusted. While it is usually preferred to hold the,

In this connection 1t will be appreciated that in the ordinary course ofshoe making` a number vof shoes of the 'same` style and having the sameheight of heel will come to the heel attaching machine in succession, so:that the clamping device, if properly adjusted for the first shoe inthe series, will, without requin ingany additional adjustments, operatein the same manner upon all of the shoes in that series.` n
